The Veiled Leopard was a full-cast audio drama initially released on CD as a bonus with DWM 367. It features Peri and Erimem in part one and Ace and Hex in part two, conducting two separate missions at the same location for their respective Doctors. Neither the Fifth nor Seventh Doctors appear, though they are referenced in dialogue.

Leopard predates the Companion Chronicles series, and differs from them in that it is a full-cast audio dramas (as opposed to most Companion Chronicles which usually feature a single narrator and a second voice). The two sets of companions never meet, although their paths do coincidentally cross once.

Following the same basic plot of The Pink Panther, it is a rare instance of a Doctor Who story in any medium being a pastiche of a comedy.

The Veiled Leopard was later made available for free download from Big Finish's Soundcloud website, and was one of several stories made available for free download with the purchase of the 50th anniversary special edition of DWM 467 in 2013.

Four time travellers. Two missions. One costumed ball. The Doctor has sent Peri and Erimem to prevent the fabulous Veiled Leoparddiamond from being stolen. Which is odd, seeing as the Doctor has sent Ace and Hex to steal the diamond. How will the two teams cope with this contradictory task? Will Peri's asp slip? Why does Ace have to pretend to be a French maid? How will Erimem cope with Pharaoh Rammalamadingdong? And can Hex really "do posh"?

The Seventh Doctor has previously talked to the Fifth Doctor about a plan to stop the theft of the Veiled Leopard, a precious diamond which contains a code to rebuild a world which was lost. They talked about returning it to its owners. Peri and Erimem stop the jewel thief and return it to its safe, completely ignorant that it is, in fact, a piece of alien technology.

Ace and Hex go to find the diamond to steal it. Luckily, this happened after Peri and Erimem stopped the jewel thief. This time, the Doctor has explained why it is so important. Unfortunately, they arrive too late and have to stop another thief who is trying to steal the diamond so that the owner can become even more rich. Ace finds a shortcut, and stops the thief, but before she can leave, she must explain herself to Peri, Erimem and a few other people.

Before the events of this story from their perspective, Peri and Erimem observed the Doctor arguing with a "kooky little guy in a weird pullover" who kept staring at them strangely. They are curious as to his identity.

Erimem now has a full head of hair and notes she has no desire to shave her head again.

Peri, Ace and Hex all refer to the James Bond film series. Peri mentions that she used to watch the films with her late father Paul Brown while growing up and compares the Casino Majestique in Monte Carlo in 1966 to the sort of venue frequently featured in the films.

Peri and Erimem on the one hand and Ace and Hex on the other observe their counterparts in the crowd several times over the course of their respective episodes but do not actually interact. Consequently, each companion pair remains ignorant of what they have in common.
